Early the next morning, Pang Xuelin, accompanied by Tao Zhexuan, first went to UCLA, met with old friends and colleagues, and then gave a lecture on Ponzi geometry theory at ULCA.

More than 500 people attended the presentation, which filled one of ULCA's largest lecture halls.

Among these people, in addition to the teachers and students of ULCA, there are also teachers and students who heard the news and rushed from the California Institute of Technology and the University of Southern California.

At the report meeting, Pang Xuelin systematically expounded the core ideas of Ponzi geometry theory and some of the latest achievements of the Ponzi geometry seminar at Jiang University in the past six months.

At the end of the presentation, many scholars who were still unsatisfied surrounded Pang Xuelin and discussed with him about the theory of Ponzi geometry.

It wasn't until about one o'clock in the afternoon that Pang Xuelin came out of the encirclement of everyone and went to ULCA's canteen with Tao Zhexuan to have a simple working meal.

After eating, Tao Zhexuan asked, "Pang, I heard that you have been doing research on carbon nanomaterials recently, do you have no new ideas in mathematics?" With your talent, it is a bit of a waste to engage in other research, and I think that if you continue to dig deeper into your Ponzi geometry, you will definitely occupy a strong mark in the future history of mathematics. ”

Pang Xuelin smiled and said: "Teacher, don't worry, mathematics is my foundation, how can I give up, it's just that the results I have launched in the past year are really a bit much, and I need to precipitate a little." My next goal, but guess! ”

"You're going to do something about Goldbach?"

Tao Zhexuan was taken aback.

If this news spreads, it will definitely cause a sensation in the mathematical community.

After all, using the big sieve method to prove Goldbach's conjecture has been walked to the end by Chen Jingrun.

Half a century later, the final step in proving Goldbach's conjecture is still far away.

Many people are vaguely aware that there is no way out of the Great Sieve method, and that if they want to prove Goldbach's conjecture, they must find another way.

But where the other way is, no one has found it until now.

Now, Pang Xuelin is ready to attack Goldbach's conjecture, which makes Tao Zhexuan look forward to it.

This super genius, who has been faintly recognized as the first person in the mathematical world today, will it still be the insurmountable mountain in front of countless mathematicians?

Tao Zhexuan was not sure.

The two chatted for a while about Goldbach's conjecture, and Pang Xuelin said: "By the way, teacher, can you do me a favor and get me a pickup truck and diving equipment, I am going to go diving in the bay near Los Angeles on the weekend." ”

"Diving?"

Tao Zhexuan was slightly stunned: "I didn't seem to have heard that you had such a hobby before." ”

Pang Xuelin laughed and said: "I learned it when I was in China some time ago, and I feel that diving is quite interesting, and it happens that Los Angeles is by the sea, and I want to feel the sea around Los Angeles." ”

Tao Zhexuan smiled: "Okay, then I'll arrange it for you as soon as possible, do you need a professional diving instructor?" ”

Pang Xuelin shook his head and said, "No, I can do it myself." ”

……

Pang Xuelin wants to go diving, naturally for the blue whale "Poseidon".

This blue whale brought back from the world of whale song is still stored in its own system space.

Pang Xuelin felt that it made no sense to let Poseidon stay in the system space all the time.

Poseidon belongs to the ocean, and without the ocean, Poseidon is no different from dead.

Therefore, he needed to find a suitable place to release Poseidon into the sea.

From the equator to the Gulf of Alaska, there are traces of blue whale life throughout the eastern Pacific Ocean, and the California Sea off the west coast of the United States is an important habitat and feeding ground for blue whales.

Now, with the strict ban on commercial whale replenishment, the blue whale population near the U.S. coastline has recovered so much that even Japanese whaling ships are afraid to show up in the area.

Therefore, taking advantage of this time to Los Angeles, Pang Xuelin decided to put Poseidon back.

And Zhizi happens to be in the United States, Pang Xuelin is ready to hand over the control of Poseidon to Zhizi, and if something goes wrong with Poseidon at that time, I believe that with Zhizi's ability, it can be solved in time.

Tao Zhexuan's movements were fast, and the next evening, he sent a pickup truck to the parking lot of Pang Xuelin's residence hotel.

"Pang, this pickup truck is my own, and there is a set of diving equipment on the body, you can just use it!"

"Teacher, then I'm sorry for you!"

Pang Xuelin invited Tao Zhexuan to dinner.

Early the next morning, he left the hotel in a pickup truck.

Not long after leaving the city, Pang Xuelin waved his hand, and Zhizi instantly appeared in the passenger seat.

"Professor Pang, are we in the United States?" Tomoko looked around and smiled faintly.

Pang Xuelin smiled: "Yes, I'm in the United States, wait for us to go diving, I'll introduce you to a new friend!" ”

"New friends?"

Tomoko was slightly stunned, a little puzzled.

Pang Xuelin smiled faintly and did not explain.

An hour later, Pang Xuelin appeared in a pickup truck near an undeveloped beach north of Los Angeles.

After Tomoko confirmed that there was no one within a few kilometers of the surroundings, Pang Xuelin handed Tomoko the wetsuit and a set of normal women's underwear and T-shirt and jeans prepared in advance, picked up the mineral water in the car, took a sip, and said: "Change your kimono, don't dress up as a Japanese woman in the future." ”

Tomoko was a little surprised: "Professor Pang, but I found that many young men on the earth like Japanese women!" Especially dressed like me! This kind of clothing seems to be particularly able to arouse the male consciousness of men. ”

"Poof!"

A mouthful of water in Pang Xuelin's mouth almost squirted out, and after a long while, he said: "Zhizi, this set of clothes is almost eliminated, and it will only be worn on some special occasions, so you won't wear it in the future!" ”

"Oh!"

Tomoko nodded and began to reach for her belt.

Pang Xuelin glared and said, "What are you doing?" ”

Tomoko said, "I'll change my clothes!" ”

Pang Xuelin said: "Wait, I'll get out of the car first!" Also, Tomoko, you remember, in the future, in public, never change clothes casually. ”

Zhizi laughed, a shy-like expression appeared on his face, and he winked at Pang Xuelin and said, "Professor Pang, I know, my body can't be shown to other people, but you are an exception!" After all, my body, mind and soul belong to you! ”

Pang Xuelin almost spurted out a mouthful of old blood, got out of the car directly, and closed the car door.

Behind him, there was a laugh like Tomoko's silver.

Pang Xuelin shook his head, he didn't know what kind of demon the system had created for him, he always felt that this Zhizi was many times higher than the Zhizi in the three-body world, both in terms of intelligence and the technological content of the parasitic body.
